I can use an extra pair of eyes solving this challenge, playground here Ultimate goal is to register functions and struct public functions into an activity manager and execute them via function name, so something along the lines of: pool := map[string]interface{ "Sample": func(ctx context.Context) error, "Sample2": func(ctx context.Context, args …interface{}) error, "SampleFromStruct": func(ctx context.Context)… Read More How to get a generic method signature using reflection in Golang
